Changes

Leak gauge is a script (available as a [http://mxr.mozilla.org/mozilla-central/source/tools/footprintleak-gauge/leak-gauge.pl?raw=1 perl script] or as [http://mxr.mozilla.org/mozilla-central/source/tools/footprintleak-gauge/leak-gauge.html?force=1 HTML and JavaScript that must be run from a local file]) that post-processes an log taken by setting environment variables in a release build. It is designed to assist in detecting what leaks of large object graphs occur during normal browsing activity. The logging can be run (as described in the script) during normal browsing without significant overhead. Then the script can be run to provide information about the documents, window objects, and docshells that leaked. See [http://www.squarefree.com/2006/01/13/memory-leak-detection-tool/ Jesse Ruderman's blog entry] for more details including a list of other links.
